Philip Glenister has revealed why he opted for an American accent to play vampire hunter Rupert Galvin in Demons.

Speaking at the press launch for the ITV1 show, the Ashes To Ashes star said: "[Rupert] was written as a Texan originally and I thought b****cks to that - I'm not playing a Texan. They said I could play him as English, but I wanted to have the challenge of playing an American."

Glenister also revealed that his American tones gained the seal of approval Stateside. "It was quite funny," he laughed, "because they sent some of the rushes to Sony in New York and this email came back from them saying: 'Philip Glenister's accent is acceptable.'"
